' 14 Claims. 1

This invention relates to improvements in containers constructed of paper for holding and for dispensing dry flowable materials such as cereals, the invention also pertaining to the form of the blank from which a container is created.

An important object is to create a blank of a single part so produced as to include an integral portion on a flap of one of the parts or sides of a. container to serve as a closure for said container.

Another object is the provision of a pouring opening in one of the walls of the container adjacent an adjoining wall, while providing on said adjoining wall a. closure adapted to cover said opening.

Still another object is to create an opening at the juncture of two of the walls of a container for discharge therethrough the contained commodity while providing on one of the walls at said opening an integral closure for the latter.

In addition, other objects will appear in the following description aided by the accompanying drawing forming part hereof.

Figure 1 is a plan of a blank in a complete whole for forming a container according to the invention.

Figure 2 shows a container in perspective during the process of folding the blank shown in Figure l, but produced on a small scale.

Figure 3 illustrates part of the container in perspective which includes a certain structure as part of Figure 1.

Figure 4 is also a perspective of the part of the box shown in Figure 3 with a closure lapped upon a side of the container.

Figure 5 is a plan in part section illustrating partsv appearing in Figures 2 and 3.

Figure 6 is a side elevation in section of partof the container showing parts illustrated in Figu'res 3 and 5.

Figure '7 is an elevation of part of the container illustrating parts appearing in Figure 3,

and

Figure 8 is an elevation in part section of part of the container in a slightly modified arrangement.

The main purpose herein is to provide a container of folded form which while furnishing any usual six sided type combines therewith on its top side an integral portion which may act as a closure for an opening created in an adjoining side, said closure forming a tight seal for said opening to exclude moisture, but which may be readily torn away, partially, to expose the opening for dispensing a commodity while yet .2 remain as part of the whole for covering said opening while the container still contains such commodity, as in the home for example.

A further purpose is that of providing an opening in the container wall from which to readily dispense a held commodity but always tightly sealed during storage of such container, and to provide a closure as an integral part of the latter, to provide such sealing while usable as a closure after unsealing.

In'Figure 1 the blank from which the container is formed, the observer views the surface that constitutes the inner surface of such container. Said blank includes the portions i and 2 as opposite broader sides of such container, together with the two narrower sides 3 and l, the former, 3, constituting what may be termed the front side which connects the said portions I and 2, while the latter, I, terminates the portion I at an edge thereof, and which has a flap 5 which overlaps an edge of the side 2 as appears in Figure 2. Terminating the ends of the portions i and 2 are flaps 6', ii and l, and a flap 1' terminates the lower end of the side 3, while flaps 6, I terminate the ends of the portion 4, the several flaps constituting the top and bottom walls of the container when folded.

In said Figure 1 the broken lines 8 indicate the score lines as the lines along which th several described portions are folded in forming the container, whereas the continuous lines 9 are the lines of severance for certain of the several portions named, as provided by the usual cutting dies, not shown.

It is now to be observed that at I0 is a portion which is part of the top portion 6' foldable along the score line 8', this said portion lil being also a part of the top portion 6 of the blank and severed therefrom on the line H. Preferably, also, this line of severance extends into the narrow side 3, a severance occurring along line I2 lying at right angles to score lines 8 of said side 3 and terminating at the score line B. By thus extending into the side 3 a tab I0 is created on said portion l0, its counterpart ill lying opposite thereto, these tabs being created along the score lines l3 and along which they are foldabie for a purpose to appear.

In thus extending the portion i0 into the portion 6 and the portion 3, two distinct advantages are gained in the container in its folded form, as will be seen in Figures 2, 4, 6 and 7 particularly. The front side 3, since the tab Ill is cut therefrom thus has an opening l4 communicating with the inner space of the container as a dmxed t the sides I and 2.

l0 and its said counterpart may overlie the sides I and 2 as suggested at H! in Figure 4, wherein the portion HI is shown folded down upon the side 3 to act as a closure for said opening it. Also, by extending the portion Ill into theportion 5 an opening I5 is created, see Figures 1, 2 and 5, which communicates with the said inner space of said container, and also with said opening H, the two openings l5 and It providing a wide pouring opening, both closed in the completely folded container by said closure portion 33. Said portion l0, when the container is closed and sealed, is itself sealed in any usual manner by the use of an adherent applied particularly to the tabs l0, Ill by which they are In opening the container to pour its contents the portion I 0 is raised and torn from the tabs along the score lines I3 thus exposing said contents, and if it is desired to remove said portion from its place entirely, it ma b torn along the score line l6 shown in Figures 1, 22nd 4.

In addition to the structure described the front side 3 may be severed in two places, for example, by diagonal lines as in Figures 1, 2 and 7 to provide the segments l8, I9, 20 which remain parts of said front sides. These may be swung outwardly or inwardly out of the plane of said side as suggested in Figure 5. When outwardly swung as in Figure 3, for example, a strip of flexible material 2| may be made to adhere to the segments, and the extremities of the strip may, if desired, be afllxed to the sides I and 2 as in Figure 5, said strip serving as a hinglng part to permit the whole to move to extreme positions.

It is observed that the segments lie in partially spaced relation and are so maintained by the strip 2 I, the latter yielding between the segments as the structure swings past the plane of the side I as it moves into or out of the container, said structure, in other words accommodating itself to the width of the space between the sides I and 2 at the front wall position without bulging said sides I and 2. When swung inwardly the described parts, of course, permit the portion III to lie flat upon said side 3. When said portion is raised, however, the described structure may be swung outwardly to form a convenient pouring spout. A structure having a pouring spout forms the subject of a pending patent application filed in the U. S. Patent Omce by the present applicant, Robert B. Cartwright, June 28, 1947, under Ser. No. 757,702, the present spout structure being an improvement thereover.

As shown in Figure 8 the front side 3' of the container may not include the spout structure just described but still use the opening I4 corresponding to II in the earlier figures. In said figure the characters 3', 6 I0 I! and I5 correspond to the parts 3, 6 IO, N and I5 respectively.

That the folding of the blank of Figure 1 so that it appears as in Figure 2 it may be stated the portion 2, as viewed, is brought toward the observer and then carried to the left over the balance of the structure whereupon the flap 5, provided with suitable adhesive, is lapped upon the free edge of said portion 2, the several'portions 8, 6', 6, and I, 1', I, as the closures for the top and bottom of the container, being then folded to their positions.

By the structure shown and described it is seen that a top portion of the container is in effect extended at one of its narrower ends to form a portion to beoverlapped upon one of the sides of such container, and that a commodity dispensing opening is covered by the same as a novel arrangement and for a new purpose as distinguished from anything in the known art.

Nothing in the structure will interfere with thepresent day method of introducing a waxed paper insert by machinery for providing a moisture proof lining, and the container has an advantage, so constructed, 'in that a permanent closure is provided as an integral part the die-cut blank from which said container is formed, while also providing for free dispensing through a large outlet and including a pouring spout at said outlet, if desired.

I claim:
